It's an Ovation Deacon XII, this one dating from between 1973-75. The Deacon was a sister guitar to the Breadwinner and was essentially a more upmarket version of that guitar featuring a natural finish (which looks positively red on this particular example), bound neck, fancier "diamond" fretboard inlays, and pearloid buttons on the machine heads. Otherwise, pickups, electrics, etc, are all the same as on the Breadwinner.
Alas, for anyone interested in this example, the auction has already finished. Sorry about that, but I thought it was still worthy of a blog post being such a nice example of this guitar.
